Fig. 11 is a detail view, scale enlarged, illustrating the constructionof the spinners and supports therefor.

Fig. 12 is a detail View illustrating-the construction of the presserdisk mechanism.

The paraflining machine is shown and described herein in connection witha machine for forming paper receptacles, as cups, a. portion of said cupforming machine only being shown, and in the drawings the numeral 10indicates a portion of the frame of such cup forming machine upon whicha turret 11 is rotatably mounted,having radial arms supporting forms ormolds 12 upon which final operations in the making of cups areperformed. As this machine forms no part of the present inventiondetails of its constructlon and 'operatlon areomitted herein, theshowing thereof being merely diagrammatic and illustrative as a meansfor supplying cups to. my improved paraflining mechanism, it being notedthat a shaft 13 on said machine constitutes a-dr'i-vy ing shaft for theparaflining machine forming the subject matter ofthis application, whichshaft 13 is driven in the regular operation of the cup forming-machineand which is for convenience merely made use of as the driving shaft forthe machine, shown and described herein. Said cup forming machine isillustrated and described in my copending application of Serial Number862,003, filed September 16/1914, and reference is hereby made to saidapplication for such an understanding of the construction and operationof said machine as may be desired, although it is believed that suchwill not be required for a complete understanding of the inventionforming the subject matter hereof, it being remarked that the machine ofsaid application comprises a support for a roll of a strip of paper 14:from which the cup bottoms are formed.

The shaft 18 is intermittently driven as I by means of intermeshingbeveled pinions (shown in dotted lines in Fig. 1) one of which pinionsis secured to a shaft 23 mounted in brackets 24 secured to the frame andhaving a ratchet wheel 25 engaged by a pawl 26 on one branch of a forkedarnr 27, mounted to rock on said shaft and connected by a rod 28 withthe shaft 13, said rod being forked to straddle the shaft 13 andengaging a carrier driving cam 29 secured thereto and by means of whichparts the carrier chain 18 given a one step movement at each rotation ofthe shaft 13, when said shaft, as in the present case, makes a completerotation each time the formation of a cup on the turret 11 is completed.

The cups 30 are forced from the nrOlds 12 by any suitable means and in amanner to fall into a. chute 31 having a flaring mouth to receive thecups and so located that a shell 21, at each time the carrier chainstops in its step-b-y-step progressive movement, is located under thedelivery end of said chute so that the cups are delivered *to and fallinto each of the shells as they pass underneath the chute and as shownin Fig. 1 of the drawings.

A presser disk 32 is loosely attached to a presser bar 33 pivotallymounted on the frame and connected by a presser rod 34 with a lever 35pivotally mounted in a bracket 36 supported on the frame 10 andconnectedat one end with a rod 37 operatively engaged with a presseroperating cam 38 secured to the shaft 13. A shell 21 is locatedunderneath the presser each time the carrier chain halts in itsstep-by-step movement and by the mechanism above described the presseris forced into contact with each cup after it has been deposited in theshell, thus pressing the cup in firm engagement with the walls of theshell so that it will not be accidentally removed therefrom.

The shaft 19 is mounted in bearing blocks 43 that may be adjusted as bymeans of screws 44 to regulate the tension of the carrier. A supportingplate 45 is mounted on the frame in position to receive and support thecups as they travel the upward reach of the chain as shown in Fig. 1 ofthe drawings. The cups pass off the end of this plate and over a paraning casing within which they are coated with parafiin. This casingconsists of a base 46 and a receiving shell 47 of cylindrical formsecured to and supported on the base. The base'46 includes a pan 48smaller in diameter than the base and secured to the upper edge of thebase, thereby forming a heating chamber 50 between the outer surface ofthe pan and the inner surface of the base. A steam pipe 51 extends intothis chamber to supply steam thereto for the purpose of heating thecontents, as wax, of the pan which heated contents pass out through adrainage pipe A spinner carrier is rotatably mounted on a supportingpost 53 rising from the bottom of the pan 48, this carrier comprising abase plate 54 and a spinner supporting plate 55 having depending flangesforming a gear chamber, which chamber is closed-by the base plate 54. Abearing and driving sleeve 56 extends from the plate 55- of the carrierand a spinner connecting shaft 57 is rotatably mounted in this sleeveand has a beveled gear 58 secured at one end meshing with a beveled gear59 on a spinner driving shaft bearing driving pulleys 60 that mayreceive a belt from any suitable source of power. A gear 61 secured tothe lower end of the connecting shaft 57 meshes with pinions 62.,securedto the ends of spinner shafts 63 rotatably mounted in spinner supportingsleeves 64 rising from the carrier and with their lower ends projectinginto hubs in the gear chamber in the carrier, as shown in Fig. 4 of thedrawings. Any suitable number (six in the construction herein shown) ofthese spinner shafts are provided, each shaft extending into a spinnerchamber 84 formed by webs 85 radially arranged and extending upwardlyfrom the plate 55, as shown in Fig. 10 of the drawings, and spinners 65are secured to the upper ends of the shafts and are of a form to receivereceptacles or cups 30 on their outer surfaces. A sprocket wheel 66 issecured. to the sleeve 56 and receives a carrier driving chain 67 ex'-tending to a sprocket wheel on a carrier driving shaft 68 mounted inbearings in brackets 6970 secured to the paraflining casing. An arch 71is secured to and extends across the upper edge of the receiving shelland contains the bearings for the up per end of the connecting shaft 57.A bracket 72 depends from the under side of said arch and contains abrake 73 that surrounds -.the sleeve 56, a bushing 74 of any suitablematerial located Within the brake being held in frictional contact withthe sleeve as by means of a clamp screw 75.

Each of the sleeves 64 has an extension 76 with a mouth 77 from which anair passage 78 leads through said extension and sleeve and opens withinthe spinners 65 that have ejecting slots 79 in their upper ends. As thecarrier is given a step-by-step rotation by means of its drivingconnection with the shaft 23 that has an intermittent movement ashereinbefore described, a mouth 77 is located, each time the carrierstops, underneath an air delivery opening 80 from a chamber 81 in a hub82 rising from a plate 83 secured to the upper edge of the shell 47 ofthe paraflining casing and projecting over the edge of said shell. Avalve case 86 is mounted for reciprocating movement in the arms 87 of abracket 88 secured to a peripheral flange extending about the upper edgeof the shell 47. The valve case has a valve chamber 89 closed by a cap90 secured to the case and receiving an air supply pipe 91 that extendsto any suitable source for air under pressure. -A valve 92 within thechamber 89 has a valve actuating rod 93 extending downwardly through anipple 94 that has its lower end extending into the chamber 81. Anactuating disk 95 on the lower end of the rod 93 is adapted to engage ashoulder in the chamber 81 at a point posite end, said arm beingpivotally supported at one end on anysuitable part of the machine, andhaving a roller 101 resting in contact with a valve operating cam 102secured to the shaft 13.

-This cam is shaped and the parts are mounted and timed in theiroperation tomove the valve case downwardly at each time a mouth 77 ispresented underneath the air delivery opening 80. In such movement ofthe case the disk 95'strikes the shoulder in the bottom of the chamber81, lifting the valve 92 from its seat and permitting air to flow intothe extension 76, which action creates a blast of air from the passage78- and within the spinner .65 thereby blowing the cup 30 from thespinner. In this upward movement of the cups from the spinner, they areguided by fingers 103 extending in a curved path to cause the cups tofall into a trough 104 by which they are delivered to any suitablepoint.

It will be noted that the spinners and the cups thereon are rapidlyrotated by the mechanism hereinbefore described and that while thusrapidly rotating the carrier containing the chambers 84 within which-thespinners are mounted is also rotated t revolve the spinners and the cupsabout t e Y axis of the carrier tobringthe spinners su cessively inposition for the different oper-'.

connected up to receive the intermittent movement imparted to thecarrier chain, makes each stop in its step by step movement with aspinner directly underneath a supporting shell, so that the cups as theyare forced from the shell drop on to the spinners and immediately takeup therotative movement thereof. The pusher 105 is located at the end ofa downwardly projecting bar from a pusher lever 106 pivotally mounted ona pusher support 107 secured to and rising from the frame, The lever 106.is actuated by a pusher rod 108 extending downwardly and having aforked end straddling the driving shaft 13 and with a roller inengagement with a pusher operating cam 109 secured to said shaft, themovements of the pusher being so timed that one. or more downwardmovements will take place during the dwell of each of the supportingshells therein.-.

After each receptacle has been deposited upon a spinner, the spinnercarrier is given a one step movement to locate the spinner in due courseunderneath a spraying nozzle 110, the, carrier rotating in the directionindicated by the arrow shown in Fig. 3. A spraying chamber plate 111 ofsubstantially the crosssectional' shape of the chambers 84 is secured tothe upper edge of the shell 47, projecting inwardly therefrom in 1 0-said chambers at the location of the airsup' ply. The nozzle'110 isconnected by pipes 113114 with a delivery pipe 115 extending from a pump116 of any ordinary construe tion and which has a pressure chamber 117the pipe 115 having a blow-ofl 118. Said pump is located ih'a wax supplytank 119 surrounded by a heating chamber 120' within a jacket 13,7 andinto which steam is introduced through a steam pipe 121 connected with amain steam supply pipe 122extending from any suitable source of steamsupply. The drain pipe 52 from the pan 48 empties into the tank 119through a troughv 138, all the surplus wax that flows ofl from the cupsin the waxing process, dropping on to the plate-55, and, passing throughstrainers 123 covering notches 124 in the edge of the disk, and in eachspinner chamber therein, flows back to the'wax'supply tank 119.

The pusher 105 is located immediately tion, the spinners continue torotate the cups to clear therefrom any surplus wax that may be containedtherein, and this takes place at the clearing station and each chamberat this point becomes a clearing chamber. The next position of thechambers as the carrier halts in its step-by-step movement is at theejection station, and as each chamber 84 comes to rest at this point andunderneath the plate 112, such chambers become ejection chambers.

The rate of rotation of the spinners and therefore of the cups thereon,is so regulated that all ofvthe surplus wax will be thrown from the cupsby centrifugal force, and the provision of a clearing station orclearing chamber enables this operation to be well done. As a furthermeans for regulating the amount of paraifin that will be deposited uponthe cups, a regulating pipe 139 is pro vided extending from the deliverypipe 115 into the tank 119, said pipe having a valve 140 for regulatingthe flow through said pipe. If this valve be open to any extent, a partof the parafiin taken up by the pump will be passed back to the tank,and the amount of flow passing through the spraying nozzle 110 onto thecups may be thus nicely regulated. I v

The pump is operated from the shaft 13 by means of a gear 125 thereon,meshing with a gear 126 on a pump actuating shaft 127 mounted insuitable bearings in the frame and having secured thereto a'crank disk128 with a slot129 extending thereacross to receive a crank block 130having a crank pin 131 projecting. therefrom. The block 130 isadjustable along the slot 129 and is secured as by means of screwspassing through slots in the disk, block, or both, as shown in Figs. 8and 9, this to regulate the amount of movement of the pump plunger. Thepin 131 engagesa yielding block 132 held between springs 133 in a pumprod bar 134 secured to an end of a pump rod 135 the other end of whichrod is connected to the plunger of the pump. This connection will permita forced stopping ofthe move ments of the pump plunger without injur tothe parts, the rotation of the crank disk being permitted under suchconditions.

The cups being delivered to the carrier 20 through the chute 31 arecarried along in the direction indicated by the arrow in Fig. 1, andsome time thus elapses between the ,delivery of the cups to the carrierand the paraflining operation, 'so that the adhesive. used in making thecups has a chance to dry before the cups are subjected to theparaflining operation.

The further operation of the machine will be readily understood it beingbriefly stated that the operation of the air valve is timed tocorrespond with the step-by-step movements of the spinner carrier sothat the air blast takes place at each time said carrier stops itsrotating movement.

In accordance With'the provisions of the patent statutes, I havedescribed the principle of operation of my invention, together with theapparatus which I now consider to represent the best embodiment thereof;but I desire to have it understood that the apparatus shown is onlyillustrative, and that the invention can be carried out by other means.
